Update:
The miles for my dine on 8/31, 9/4, and the bonus awarded 9/9 were all "paid" on 9/11.
It's 9/14, and it still hasn't shown up on my UA MP account yet as award miles. How long does it take for that the credit? I have confirmed that I have the correct FF# on the account, and that the cards I used were registered on that account.
